5.0 OPERATING THE UNIT
To use any of the HDA series HDMI Distribution Amplifiers, connect an HDMI approved
cable, no more than 50 feet in length, from the HDMI source to the input of the Distribution
Amplifier. Next, connect the outputs of the Distribution Amplifier to their destination devices
using HDMI approved cables no more than 50 feet long.* Lastly, connect the power adapter,
first to the AC source and then to the Distribution Amplifier. Turn on the HDMI source as
well as the HDMI destination devices and you will see the source signal appear on the
inputs of all of the destination devices and an LED will light indicating which outputs are
active.
*Note: Proper operation of HDMI Distribution Amplifiers depends on the use of the highest
quality cables available. HPC HDMI cables provide low loss, high bandwidth signal
handling and are the recommended cables for use with all HDMI products. The distance
specification cannot be guaranteed unless HPC cables or equivalent are used throughout
the system.
5.1 Resolution Tracking
Since HDTV can be any of several different resolutions, the HDA series Distribution
Amplifier must be able to sense and process the various resolutions on both input and
outputs. On the input, the Distribution Amplifier will sense and accept any standard
resolution however, on the outputs, the DA must sense the resolution capabilities of all of
the display devices connected to it and then set the resolution of all outputs to the
resolution of the display having the lowest resolution response characteristics. To do
otherwise would mean that some display devices would not produce a picture. The user is
advised to use display devices having the same resolution to avoid the Distribution
Amplifier’s processing circuitry assuming the lowest common denominator status on all
monitors with respect to display image resolution.
6.0 TROUBLESHOOTING
In the event of problems, first make certain that the input cable is no more than 50 feet long,
none of the output cables are more than 50 feet long and all cables are of premium
construction such as HPC or equivalent.
Next, you should be check the power button could be using or not, and make certain that
the Distribution Amplifier is receiving power by looking at the power LED. It should be
illuminated and not flickering or intermittently going on and off. Intermittent operation
generally means a problem with the DC adapter or low AC voltage being applied to the DC
adapter’s input.
If all is well in these areas, remember that HDMI devices communicate with one another so
the source device and all destination devices must be fully HDMI capable. In addition,
HDCP encryption requires additional processing which also is dependent on the equipment
you have connected to both the source and destination devices. If you experience
